Stuart and Schmeky--I tested an extended pin and a light spring with both 13 and 15 lb hammer springs without total success, I'm afraid. I would have to check my notes, but I think the 15 was good for about 90-95% firing and the 13 was not usable. I went back to a 17 hammer spring. I think that is correct.

I would love to be able to use the same springs as for a competition gun, but I don't know how to do it.

I've had this on the back burner for a while (sadly, making a living takes up my time lately).Joe is right, the FP isn't a one part solution.

1st - You have to make sure that the barrel is location properly, so that the bolt impacts the slide, not the chamber end of the barrel.2nd - Extended Firing Pin (for experimentation, it would be nice to have the same lengths but one standard weight and another lightened version.)3rd - Reduced power firing pin spring4th - (possibly) heavier hammer itself

If someone gets it sorted out, I'd be in for one. My Shadow is great with the Shadow slide, but I tend to get several light strikes every magazine with the Kadet slide. I could up the main spring, but I like the trigger the way it is.

I will echo everybody else's comments. If you guys can work out an extended fp/ spring combo to get us down to just 15lb main spring I would be all over it. I have a 18lb ms in now to make the kadet 99%reliable, but really is a disservice to all of Stuart's hard work on the light DA pull.
